In Denmark May 12, 1937 2 Claims.

The present invention relates to an improved support for a self-winding recording device or the like that is subjected to a horizontal pull for extracting the recording strip, and which sup- 5 port is preferably intended for combining such recording devices with a telephone apparatus disposed upon a fiat base, for instance a table top.

The hitherto known supports for combining such devices to telephone apparatus or the like are subjected to the essential drawback that they are either screwed to or clamped to a part of the telephone apparatus in close proximity to the metal cradle for the receiver. This manner of attachment is inconvenient and necessitates l5 furthermore that the construction of the support must be adapted to the various types of telephone apparatus. Finally there is some danger of damaging the metal parts of the telephone apparatus by employing screws and 5 clamps.

The object of the present invention is to provide a support for a self-winding recording device in which the inconveniences connected with the supports of known construction are eliminated,

25 and which support is simple in construction and adequate in form and may be applied to a telephone apparatus of any of the types in general use, without therefore causing any damage to or inconvenience in the use of the telephone apparatus.

The characteristic features of the support according to the present invention are that the support comprises a member formed to the shape of an angle lever with a horizontal arm adapted 35 to be inserted between the base of a telephone apparatus and the surface of its supporting base, a bracket formed upon the upper end of the other vertical arm, and a recording device disposed on and attached to the bracket.

In one particular manner of construction of the support according to the invention there is attached to the horizontal arm a rearwardly extending spring member, to the extreme end of which a clamp member is attached, and which clamp member in connection with the vertical arm of the angle lever serves to clamp the support to a telephone apparatus when the horizontal arm is applied to the base thereof, thus al- 5 lowing its removal together with the telephone apparatus.

In a support of this kind in which the bracket for holding the recording device is raised somewhat above the member inserted between the 55 telephone apparatus base and its supporting base, a horizontal pull exerted on therecording strip for extracting it from the holder will effect an action as a bell crank lever by which the horizontal member will be pressed upwards against the telephone apparatus base, the angle 5 between the horizontal and the vertical arms serving as fulcrum. The friction members provide an increased friction between the support and the telephone apparatus base, and by means of the spring member this frictional action is furthermore increased.

Further details of construction are provided in the following description in view of the accompanying drawing, in which:

Fig. l is a side elevation of a support disposed between a telephone apparatus and its supporting base.

Fig. 2 is a top elevation of the support shown in Fig. 1.

In the manner of construction of the support illustrated in Figs. 1 and 2, the base portion is indicated by 6 and the upright portion by I. The base portion 6 is inserted in Fig. 2 between the base of a telephone apparatus 8 and its supporting surface 9, the telephone apparatus being provided with feet It! by means of which it is slightly raised from its supporting base. The upright portion I has on its upper end somewhat higher than the base portion 6 a bracket II, to the upper side of which there is attached a selfwinding recording device i2 of known construction. The front edge of the recording strip included in the recording device is indicated at l3, and for extracting the strip a pull thereon is exerted in the direction indicated by the arrow in Fig. l. The base member 6 is provided with two frictional members l4 disposed in a line parallel with the angle bend between the base 6 and the upright portion 1, and the line a-a in Fig. 2, through these friction members l4 indicates the axis on which the angle member 6, I has a tendency to be tipped. The rear end of the base 6 has two extensions 6a and 6b to the upper side of which there are affixed friction members 15 at the ends thereof. Upon exerting a pull on the recording strip l3 in the direction of the arrow, the support will turn on the fulcrum line aa, and by this there is exerted on the base 6 a tendency to turn in the opposite direction to that of the pull exerted on the recording strip and the horizontal portion 1.

The base portion 6 has an aperture N5 of a size large enough to encompass one of the feet H] of the telephone apparatus 8, thus allowing the 55 arrangement of the support at one of the corners of the telephone apparatus.

To the lower side of the base portion 6 there is furthermore attached a spring I! extending rearwardly beneath the base of the telephone apparatus, and to the free end of the spring there is attached a clamp l8, which is formed to engage the rear end of the telephone apparatus, and by means of the tension of the spring H the support is clamped to the telephone apparatus between the clamp l8 and upright portion 7.

Finally there is attached to the lower side of the portion 6 a leaf spring 19, on the lower side of which there is attached a friction member 20, and this spring serves to press the portion 6 against the lower side of the telephone apparatus, even if no pull is exerted on the recording strip.

It will be understood that even if the support according to the present invention is described in connection with a telephone apparatus, it may be employed in connection with any other suitable device that allows its arrangement in such a manner that the horizontal portion is inserted between the base of the device in question and the supporting base for same.

I declare that what I claim is:

1. A support for a self-winding recording device that is subjected to a horizontal pull for ex tracting the recording strip, comprising a plate member for insertion between a telephone apparatus and the surface of its supporting base, an projecting approximately at a right angle from the one edge of the plate member, a recording device of known construction attached to the said arm, and friction members attached to the lower and upper sides of the plate member.

2. A support for a self-winding recording device that is subjected to a horizontal pull for extracting the recording strip, comprising an angularly bent plate member having a horizontal and a vertical portion, frictional members attached to the lower side of the horizontal portion along the bent edge, extensions formed on the opposite edge of the horizontal portion, frictional members attached to the upper side thereof, a leaf spring attached by its one end to the lower side of the horizontal portion between the frictional members and extending beyond the extensions, a frictional member attached to the free end of the spring on the lower side thereof, a bracket attached to the upper end of the vertical portion of the bent plate member, and a recording device of known construction attached to the bracket.
